[0001] This utility model relates to the field of aerosol generation technology, and in particular to an aerosol generation product. Background Technology

[0002] Currently, aerosol-generating products (such as non-combustible tobacco matrix) can be heated at lower temperatures, allowing them to release tobacco-flavored aerosols that are delivered to consumers without combustion, thus replacing combustible tobacco products. In existing technologies, air channels are incorporated into the aerosol-generating matrix section of the aerosol-generating product, making assembly and filling the aerosol-generating matrix more complex. Furthermore, the compression and deformation of the air channels can easily reduce inhalation stability. Summary of the Invention

The functional section and the aerosol generating matrix section are respectively connected to opposite ends of the support section. The blocking section is located at the upstream end of the aerosol generating matrix section and is used to block the aerosol generating matrix section.

[0024] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] like Figures 1 to 5 As shown, this utility model embodiment provides an aerosol generating article, including an aerosol generating matrix section 100, a support section 200, a sealing section 300, and a functional section 400. The functional section 400 and the aerosol generating matrix section 100 are respectively connected to opposite ends of the support section 200. The sealing section 300 is made of a high-temperature resistant material and is located upstream of the aerosol generating matrix section 100, and is used to seal the aerosol generating matrix section 100. A central gas... The supporting section 200 has an air inlet 230 on its outer wall, which connects to the inlet of the peripheral air duct 220. The outlet of the central air duct 210 is located at the downstream end of the supporting section 200 and connects to the functional section 400. The inlet of the central air duct 210 and the outlet of the peripheral air duct 220 are both located at the upstream end of the supporting section 200. The outlet of the peripheral air duct 220 is connected to the inlet of the central air duct 210 through the aerosol generating matrix section 100. In the design of the aerosol generating product of this utility model, the starting section in the direction of aerosol flow towards the functional section 400 is defined as the upstream end, while the direction of aerosol outflow is defined as the downstream end.

[0026] Understandably, the aerosol generating matrix 600 is made from plant (such as tobacco) leaves and / or stems, and is a solid material that can be processed into various forms such as filaments, sheets, or integral molding, and can be supplemented with aroma and other ingredients to enhance the sensory experience. In these forms of solid materials, gaps are left between the sheets or micropores are contained in the integral molding material, which together form airflow channels to promote the effective generation and transport of aerosols.

[0027] Specifically, the aerosol generating product is generally inserted into the receiving cavity of the aerosol generating system during use. The sealing section 300 is used to seal the bottom of the aerosol generating matrix section 100, preventing the aerosol generated by heating and baking from overflowing from the bottom of the aerosol generating matrix section 100. This effectively prevents the aerosol generating matrix 600 and the heating element 500 from falling off, thus preventing the aerosol from condensing and depositing in the receiving cavity of the aerosol generating system, thereby contaminating the receiving cavity and causing cleaning problems. Furthermore, when the aerosol generating product is inserted into the receiving cavity of the aerosol generating system, the air inlet 230 is not blocked by the aerosol generating system, that is, the air inlet 230 is exposed to the aerosol generating system, allowing outside air to enter the aerosol generating product through the air inlet 230.

[0028] The functional section 400 is provided with an airflow channel for users to inhale the aerosol generated by the aerosol generating matrix 600. The functional section 400 can be configured with different functions to improve the user experience, such as filtering impurities in the aerosol during inhalation or cooling the aerosol gas. The connection method between the functional section 400, the support section 200, the aerosol generating matrix section 100, and the sealing section 300 includes, but is not limited to, one or more methods such as bonding or splicing, as long as a stable connection can be maintained. The cross-sectional area and number of the central air channel 210, the peripheral air channel 220, or the air inlet 230 can be set according to actual needs to meet the gas flow requirements of the aerosol generating product. The lengths of the aerosol generating matrix section 100, the support section 200, the sealing section 300, and the functional section 400 can be set according to actual needs.

[0029] In one embodiment, the length of the aerosol generating matrix section 100 ranges from 8 to 15 mm, the length of the support section 200 ranges from 13 to 27 mm, the length of the sealing section 300 ranges from 3 to 7 mm, and the length of the functional section 400 ranges from 7 to 10 mm.

[0030] like Figures 1 to 5 As shown, in one embodiment, the support section 200 is provided with a plurality of peripheral air channels 220 and a plurality of air inlets 230. The plurality of peripheral air channels 220 are arranged at intervals around the central air channel 210. Each peripheral air channel 220 is connected to the outside through at least one air inlet 230, so that outside air can enter the aerosol generation matrix section 100 more smoothly.

[0031] like Figures 2 to 5As shown, in one embodiment, the central airway 210 is an airflow hole that passes through the support section 200, thereby facilitating communication between the support section 200 and the functional section 400 and the aerosol generating matrix section 100.

[0032] In this embodiment, the aerosol generating matrix section 100 has an internal gap after storing the aerosol generating matrix 600, and the outlet of the peripheral airway 220 is connected to the inlet of the central airway 210 through the internal gap. During user aspiration, as... Figures 2 to 4 As shown by the dashed arrow, the airflow enters the peripheral air passage 220 through the air inlet 230, and after carrying aerosol through the internal gap, it enters the central air passage 210 and is then drawn out by the user from the functional section 400.

[0033] In the aerosol generating article of this embodiment, the central airway 210 and the peripheral airway 220 are disposed on the support section 200, and the inlet of the central airway 210 and the outlet of the peripheral airway 220 are both disposed on the end face of the support section 200 away from the functional section 400. Specifically, the central airway 210 and the peripheral airway 220 are only disposed on the support section 200 and do not extend to the aerosol generating matrix section 100. Since there are no airway cavities on the aerosol generating matrix section 100, it is not easily deformed after being squeezed, which improves the stability during user aspiration. When assembling the aerosol generating article, it is easier to assemble the aerosol generating matrix section 100 with the support section 200, which improves the assembly efficiency of the aerosol generating article. At the same time, when filling the aerosol generating matrix 600 into the aerosol generating matrix section 100, it is not affected by the central airway 210 and the peripheral airway 220, which improves the filling efficiency of the aerosol generating article.

[0034] like Figures 2 to 5 As shown, in one embodiment, the air inlet 230 is located at the end of the peripheral airway 220 away from the aerosol generating matrix section 100. Understandably, the airflow is at a lower temperature when it enters the peripheral airway 220 from the outside through the air inlet 230, and at a higher temperature after carrying aerosol through the internal gaps of the aerosol generating matrix section 100 and entering the central airway 210. Both the central airway 210 and the peripheral airway 220 are located on the support section 200. Therefore, the cold air in the peripheral airway 220 can cool the hot air in the central airway 210. In this embodiment, placing the air inlet 230 at the end away from the aerosol generating matrix section 100 extends the length of the peripheral airway 220, thereby further improving the efficiency of cooling the hot air in the central airway 210 by the cold air in the peripheral airway 220, and avoiding problems such as scalding the mouth when inhaled due to high temperature.

[0035] Figures 2 to 5 As shown, in one embodiment, a heating element 500 is provided within the aerosol generating matrix section 100. The heating element 500 is used to heat the aerosol generating matrix section 100 to generate aerosols. It is understood that the structure of the heating element 500 can be configured according to actual conditions, as long as it can heat the aerosol generating matrix 600 in the aerosol generating matrix section 100. The heating element 500 can be a magnetic metal component that heats up under electromagnetic induction. In one embodiment, the length of the heating element 500 is equal to the length of the aerosol generating matrix section 100, thereby allowing for more uniform heating of the aerosol generating matrix 600 in the aerosol generating matrix section 100.

[0036] like Figure 2 , Figure 3 and Figure 5 As shown, in one embodiment, the sealing segment 300 is a solid sealing structure. Figure 4 As shown, in one embodiment, the sealing section 300 is in the shape of a hollow spherical crown. In both embodiments described above, air will not enter the aerosol generating matrix section 100 from the upstream end of the sealing section 300.

[0037] like Figure 4 As shown, in this embodiment, the sealing section 300 is a sealing structure with a cavity. The sealing section 300 has an opening facing the aerosol generating matrix section 100. After the sealing section 300 is connected to the aerosol generating matrix section 100, it can effectively prevent the aerosol generated by heating and baking from overflowing from the upstream end of the aerosol generating matrix section 100, thereby reducing heat loss. Understandably, the aerosol generating product is usually inserted into the receiving cavity of the aerosol generating system during use. At this time, the function of the sealing section 300 is to seal the upstream end of the aerosol generating matrix section 100, prevent the aerosol generated by heating and baking from leaking from the upstream end, and at the same time prevent the aerosol generating matrix 600 and the heating element 500 from falling off, ensuring that the aerosol can be deposited in the cavity after condensation, preventing it from contaminating the receiving cavity of the aerosol generating system, thereby avoiding the problem of difficult cleaning.

[0038] like Figures 3 to 5As shown, in one embodiment, the support segment 200 includes a first support body 240 and a second support body 250. The first support body 240 is arranged around the outside of the second support body 250. The air inlet 230 is disposed on the first support body 240, the central air passage 210 is disposed in the second support body 250, and the peripheral air passage 220 is disposed between the second support body 250 and the first support body 240. It is understood that the shapes of the first support body 240 and the second support body 250 can be set according to actual conditions, such as hollow cylinders, cuboids, or irregular shapes. The peripheral air passage 220 can be disposed on the second support body 250, on the first support body 240, or on both the first support body 240 and the second support body 250, as long as a peripheral air passage 220 can be formed between the second support body 250 and the first support body 240.

[0039] like Figure 5 As shown, in one embodiment, a first air guide groove 241 is provided on the inner side wall of the first support 240. The first air guide groove 241 and the outer side wall of the second support 250 form the peripheral air passage 220.

[0040] like Figure 3 and Figure 4 As shown, in one embodiment, a second air guide groove 251 is provided on the outer side wall of the second support 250, and the first support 240 and the second air guide groove 251 form the peripheral air passage 220.

[0041] like Figures 3 to 5 As shown, in one embodiment, the inner sidewall of the first support 240 is provided with a first air guide groove 241, and the outer sidewall of the second support 250 is provided with a second air guide groove 251. The first air guide groove 241 and the second air guide groove 251 form the peripheral air passage 220.

[0042] This utility model embodiment also provides an aerosol generation system, including the aforementioned aerosol generation product. The aerosol generation system may further include necessary components such as a battery, buttons, a control board, and a housing, which will not be described in detail here.

[0043] In the aerosol generation system of this embodiment, the central airway 210 and the peripheral airway 220 are disposed on the support section 200, and the inlet of the central airway 210 and the outlet of the peripheral airway 220 are both disposed on the end face of the support section 200 away from the functional section 400. Specifically, the central airway 210 and the peripheral airway 220 are only disposed on the support section 200 and do not extend to the aerosol generation matrix section 100. Since there are no airway cavities on the aerosol generation matrix section 100, it is not easily deformed after being squeezed, thus improving the stability during user aspiration. When assembling the aerosol generation product, the aerosol generation matrix section 100 and the support section 200 are easier to assemble, improving the assembly efficiency of the aerosol generation product. At the same time, when filling the aerosol generation matrix 600 into the aerosol generation matrix section 100, it is not affected by the central airway 210 and the peripheral airway 220, thus improving the filling efficiency of the aerosol generation product.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
